not only drinkingwater may be the outcome of this theoretical $4 device. one obsticle to produce cheap hydrogen is that one can not just apply electrolysis to salt water. and many areas with lots of sunlight have limited freshwater to split into its atomic compounds.
i am thinking large scale solar in the sahara, used for electrolysis of mediteranian and atlantic sea water |
